MP100 High Gloss Stainless Steel Tubes Mirror Polishing Machine

Stainless steel tube mirror polishing is an important process for tube manufactures. Mirror polishing stainless steel tube creates a uniform and consistent shinny surface finish which is essential for several industries both for aesthetic and technical reasons.

Stainless steel tubes before and after MP100 - Mirror Polishing Machine 
Industries such as stainless steel tubular furniture, bull bars and bumpers for off road cars or boat railings are some examples which often require tube mirror polishing, either for enhancing the looks of an item by creating a reflective surface or for preventing corrosion in tubes and pipes.

Although stainless steel is much more resistant to corrosion than ordinary carbon or alloy steels, in some circumstances it can corrode. Coastal line stainless steel tube constructions, such as outdoor stainless steel railings or marine fittings require a smooth mirror polished finish so it gets harder for the corrosion to stick into the stainless steel tubes. Smoother surface will bring a better staining resistance. A similar effect happens in process industries such as food and pharmaceutical, where improving the surface quality up to mirror polishing will decrease the risk of bacteria to remain on the stainless steel.

So far many solutions for mirror polishing stainless steel tubes were centerless tube mirror polishing and buffing machines. This technology forces the tube to spin while it passes through the polishing wheels. Although effective this method brings some restrictions on the type of tubes which can be mirror polished. Within this range of products we can enhance long tubes which tend to vibrate unless supported in bulky guiding tables and curved tubes which, due to its geometry, just cannot be turned around the polishing wheels.

MP100 is a revolutionary concept which is able to mirror polish stainless steel tubes by inverting the existing model of the tube polishing market. Instead of forcing the tube to spin so the contact is made with the stationary polishing station, MP100, has changed the existing technology by making the polishing buffing wheels rotating around the tube.

Producers of curved tubes products in stainless steel such as off road cars accessories (namely bull bars and sports bars), bathroom and kitchen taps, high class architectural balustrades and fittings or swimming pool ladder rails commonly face the problem of applying the final mirror polishing in their bent tubes. This job is typically made with manual machines which end up being a very time consuming and labor intensive process.

With MP100 three planetary polishing wheels rotate around the tube making high pressure and delivering a high gloss mirror polishing in straight but also in curved tubes. The operator simply needs to transport trough the polishing head, while the cotton wheels do their job on the complete external diameter of the tube, completing a consistent finish both on the outer but also on the inner side of the bend.

Additionally the machine features an automatic feeding system which transports straight tubes safely through the polishing units, enabling a consistent and high gloss mirror polishing quality in a vibration-free process. The feeding systems are assembled in hinges and can be assembled or removed in few seconds, making this machine flexible for multiple operations.

The design of MP100 assures that, as opposed to centerless machines where a work rest is used, no tube support is located on the polishing area. As a consequence NS Máquinas tube mirror polishing machine assures no marks, no scratches and a perfect tube polished surface.

The machine features brushes pressure control by foot pedal which enables the operator to control the applied force during tube polishing operation.

In order to achieve a shiny surface the machine is equipped with automatic solid polishing compound system. The operator can define the quantity of compound to be applied and simply start the process when it is required.

MP100 has a working capacity on straight tubes up to Ø114mm and was developed to polish different geometries for curved tubes. Depending on the quality of surface which is requested and on the shape of the tube, MP100 can mirror polish up to a speed to 3 linear metres per minute, turning tube mirror polishing a more practical, fast and safe operation. Definitively a great improvement for any company doing stainless steel tubes.

See the demonstration video below with the areas of application for the MP100 tube polishing machine: bull bars mirror polishing, automotive components mirror polishing and stainless steel furniture mirror polishing.

MLW200 TC: The Automatic Solution for Conic Poles Finishing



MLW200, TC version, is a round tubes finishing machine capable of polishing automatically cylindrical and conical tubes from Ø25mm up to Ø205mm. 

This machine was designed to finish conic tubes without any manual adjustment making possible to polish a complete pole starting with Ø165mm and ending up to Ø75mm. 

This is particularly interesting for light poles polishing production where most of them are tapered and need to be finished and polished prior to painting or coating. Also, some aluminum poles require an abrasive belt polish only for aesthetic reasons. 

The finishing radial lines are applied regardless the light poles length. Often, light poles are 14 meters long and the complete surface needs to be finished on a polishing machine.




The feeding units features a precise diameter compensation system which, combined with the solid structure, assures a vibration-free and safe tube transport operation. 

Having a water cooling spray on the finishing area MLW200 TC can polish different metals and safely work potentially explosive materials. One automatic filtration and pumping system is integrated in the machine frame and can be easily removed for cleaning. 



MLW200 TC offers a fast and reliable process up to 4 meters per minute.  Simultaneously it assures a constant finishing even along the biggest lengths. 

See the demonstration video of MLW200 TC machine where aluminum light poles are polished and contact us at marketing@nsmaquinas.com or further information on this tube polishing machine.
